New Jersey Truck Idling Law

New Jersey is one of the strictest states at 3 consecutive minutes (N.J.A.C. 7:27-14 and 15, the Stop the Soot program). A truck stopped 3 or more hours can idle up to 15 minutes when it is below 25F, and sleeper-berth rest is allowed for 2007-and-newer engines or trucks with a working DPF outside residential areas. Fines climb from $250 to $500 to $1,000. APUs and bunk heaters are exempt.
